Carpenter Square Reviews

There are several different types of carpenter squares, each of which are practical for their own set of uses. The original Swanson speed carpenter square is what many people think of when they picture a carpenter square and are particularly useful for roofing carpentry work. They work well in conjunction with a circular saw to cut a piece of wood perfectly square, and in that sense they also can double as tri squares. More often than not, carpenter squares are used to lay out and cut roof rafters and to make sure that right angle cuts are precisely squared. Additionally, carpenter squares are among the only tools in a toolbox with a straight edge (3 of them) and right triangular shape.

Woodstock D4089 Machinist Square Set

5/5 Product Rating

Machinist squares are basically just a try square used by metalworkers. They feature a simple design that consists of a long steel arm that is affixed to a heavier steel body at a 90-degree angle. To use a machinist square, you place the body of the square along the side or edge of an object and you lay the edge of the arm along that same side. You can then shine a light behind the square and if there is any present, the object is not square. This 4-piece set of machinist squares from Woodstock includes four squares of varying sizes, all of which share a common beam width and thickness, allowing them to be used together on the same project. The sizes are 2, 3, 4, and 6-inches, and you can tell just by looking at them that the metal was milled correctly. Test them a little further and you’ll see that they come square and true and will stay that way use after use.

  • 4-piece set includes 2, 3, 4, and 6-inch machinist squares
  • Squares share common beam width and thickness, no variation aside from height
  • Machined well, come square
